IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 126,952, dated May 21, 1872.

improved hill-side plow, simple in construe-- tion and convenient in use, being easily and quickly adjusted as a right or left hand plow, and being securely and firmly held in place when adjusted; and it consists in the construction and combination of various parts of the plo-w, as hereinafter more fully described.

A is the plow-point, which is made triangular in its general form; two of its sides are made flat to serve alternately as base and landside; the third side is concaved to adapt it to serve as the forward part of the mold-board in either adjustment. B is an angle-plate, formed upon orV attached to the rear end of the point A, at the angle between its plane sides, the wings of which plate serve alter-- nately as base and land-side. C is the standard, which has a brace, D, formed upon or attached to it, which brace projects to the rearward and curves downward, as shown in Fig. 1. The lower ends of the standard C and brace D are pivoted to a rod, E, the forward end of which is attached to the rea-r part of the point A, near the angle between the plane sides of said point. The rod E extends back along` the angle of the .base-plate B, audits rear end is attached to a transverseplate or flange, F. The upper or third side of the plate F is 1made concave or angling, and its ends or corners project above the edges of the base-plate B, as shown in Fig. 2. Gr is the V- shaped or double mold-board, the sides or win gs of which are made straight and plain, so that each of the said wings may serve alternately as a mold-board and a land-side, as the plow is adjusted to turn the furrow to the right or left. The V-shaped mold-board G is hinged to the forward edge ofthe standard G by two 'curved pins or rivets, H, which pass through holes in the said mold-board and standard, and the ends of which are riveted or headed down upon the said mold-board so as to leave its outer surface smooth. I is an angular bar, made in about the form shown in Fig. 2, and the ends of which are securely bolted or riveted to the wings or mold-boards 'Gn The upper edge of the end parts of the bar I is made straight and horizontal to receive and ht against a shoulder, d', formed upon the rear edge ofthe brace D. Upon the lower edges of the end parts ot' the bar I are formed recesses to receive the angles or corners ofthe ange or plate F, as shown in Fig. 2. J are lever-latches7 pvoted to the rear side of the bar l', near its ends, in such positions that when either win g of the double moldboard G isnioved up against the side of the brace D the end of a latch, J, may take hold ofthe edge of the shoulders d of said brace, and lock the various parts ofthe plow securely together. By this construction, by raising the free end of the lever-latch J the parts of the plow will be released, so that it may be conveniently turned or adjusted to turn the furrow in the other direction. The free or inner ends of the lever-latches J are weighted to hold them in place, and cause them to take hold of the shoulder d automatically as the parts come into place.

Having thus described my invention, I claim as new and desire to secure by Letters Pat ent- A s l. The point A, angular base B, standard and brace U D, and V-shaped or double moldboard Gr, constructed and arranged, in connection with each other, substantially as herein shown and described, and for the purpose set forth.

2. The flange or plate F and bar I, constructed and arranged, in connectiongwith the angular base B, V-shaped or double moldboard G, and brace D d', substantially as herein shown and described, and for the purpose set forth.

3; The weighted lever-latches J, in combination with the bar I, and shoulder d formed upon the brace-bar D, substantially as herein shown and described, and for the purpose set forth.
